IMPROVEMENT IN SH UTTER-FASTENINGS:

Specification forming part of Letters Patent No. 40,868, dated December 8, 1863 To all whom, it may concern:

Be it known that I, T. J. TowNsEND, of Baltimore, in the county of Baltimore and State of Maryland, have invented a new and improved apparatus or device for opening and closing window shutters and blinds and for securing them at any desired point between an open and a closed state; and I do hereby declare that the following is a full, clear, and exact description ofthe same, reference being hLd to the accompanying drawings, making' a part of this specification, in which- Figure l is a plan or top view of my invention applied to a window/shutter; Fig. 2, an enlarged plan or top view of the same. with the cover of the box or case removed 5 Fig. 3, a section of Fig. 2, taken in the line x :12.

Similar letters of reference indicate corre spending parts in the several figures.

This invention relates to a new and improved deviee for opening and closing window shutters and blinds, and for securing them at any desired point between an open and a closed state from the inner side of a room without raising the sash.

The invention consists in the employmentor use of a chain attached at one end to a sliding bar and attached at the opposite end to a wheel provided with a shaft or arbor, on which the lower hinge of the blind or shutter is fitted, all being arranged and applied, as hereinafter shown, to effect the desired end.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents a wheel, which is fitted on a square arbor or shaft,` B, the wheel being placed in acircular case or box, O, communicating with a square pipe, D, in which a sliding bar, E, is fitted. The inner end of the bar E has a chain, F, attached to it, and this chain is connected to the periphery of the wheel A, as shown at a, the chain extending around a greater or less port-ion of the periph- I claim as new, and

ery of the wheel, between it and the inner side of the box C, as shown clearly in Fig. 2.

The bar E is provided with a joint, b, to admit of its outer part being turned down out of the way when the bar is drawn out, so that thejoint b is out from thepipe D. One side of the bar E is notched at equal distances apart, as shown at c in Fig. 2, in order to admit of a Spring bolt or pin falling into any one of them, to retain the bar at any desired point. This pipe D is placed or fitted on the sill of the window and passes underneath-the side of the window-frame at such a point as to bring the shaft B directly under the hinge F of the shutter or blind, the hinge being provided with a tube, d, having a square interior to t on the shaft B. n

From the above description it will be seen that by grasping the end of the bar E, which is within the room, and shoving it in or withdrawing it from the pipe D, the shutter or blind may be opened and closed with the greatest facility and without raising the lower sash, and by having a suitable catch or fastening applied to the bar E the blind or shutter may be retained or held at any desired point between an open and a closed state. This arrangement, it is believed, is far simpler and less liable to get out of order than any hitherto devised for the same purpose.

Having thus described my invention, what desire to secure by Letters Patent, is-

The wheel A, chain F, and bar E, placed respectively within a case, O. and pipe D, in connection with the hinge F of the blind or shutter, applied to the wheel A or shaft B thereof, the case and pipe peing applied to the windowframe, and all arranged substantially as and for the purpose herein set forth.
